> Key: AMQ-5714
> URL: https://issues.apache.org/jira/browse/AMQ-5714
> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.11.1
> Reporter: James Spurin
> Priority: Minor
> Fix For: Unscheduled

> Original Estimate: 1h

> The pathCanonical method does not work as expected for directories that
> contain either single characters or 2 characters. This is caused by the
> following entry -
> {noformat}
> echo "${dst}" | sed -e 's#//#/#g' -e 's#/./#/#g' -e 's#/[^/]*/../#/#g'
> {noformat}
> This can be resolved with the following changes -
> {noformat}
> echo "${dst}" | sed -e 's#//#/#g' -e 's#/\./#/#g' -e 's#/[^/]*/\.\./#/#g'
> {noformat}
> Example, before and after -
> {noformat}
> # echo /1/2/3/4/11/22/33/44/.././x | sed -e 's#//#/#g' -e 's#/./#/#g' -e
> 's#/[^/]*/../#/#g'
> /2/22/../x
> # echo /1/2/3/4/11/22/33/44/.././x | sed -e 's#//#/#g' -e 's#/\./#/#g' -e
> 's#/[^/]*/\.\./#/#g'
> /1/2/3/4/11/22/33/x
> {noformat}
